As stated above I have gotten rid of the humming sound somewhat, but not from changing outlets.

When playing the ipod, there I can tell that "something" is getting to the subs but not "everything"... so there is somewhat of a continuous rumbling effect that will go to the beat of the music, then, when I crank up the volume, I get the thump the 800 is supposed to give...

once I turn up the volume and get the music bass, i can then turn it down and the 800 will still respond to the bass.

okay, now i'm stumped! If I play a movie in the ps3 I get the bass, if I put in a music cd in the ps3 all the bass passes through the m80s??? wtf??? Does that make sense to anyone? I know it must be a setting, no?

Dont use your iPod as the source. Use the PS3. There is probably a setting on the iPod that is causing problems. The PS3 is a much better source to use anyways. So you are getting bass now but is there still unwanted noises such as humming or anything else that sounds strange such as distortion?

What does your receiver say when playing a CD? Mine always defaults to "Direct" when playing a CD on my PS3, and I usually change it to a matrixed multichannel mode after the fact. There may be a way to choose a different default based on what type of signal it's receiving, but I've been too lazy to investigate. It might be something to look into on yours.

yeah, I thought I had solved the problem but put finding nemo in the ps3 and when the bird hit the window the helicopter effect happened again, but then when they did the initiation in the fish bowl (I think that's the scene SRoode mentioned) the sub was CRAZY thumping!! I was seriously impressed!! So I'm kind of at a loss for what causes the problems.

As for the music, that's what I did... popped in a cd and nothing... at all! all the bass was passing through the m80s!

and the m80s are set to small. would the setting change on it's own when it's a music cd?
